Question
Describe which molecules are phosphorylated in gene regulation, whether the level of methylation will increase or decrease, how the flagella will turn, and how the cell will move when it has just moved from low to high concentration of chemoattractant. Answer the same question if the cell is in a constant concentration of chemoattractant or if it moves from high to low concentrations of chemoattractant. Answer the same questions for repellent and describe what happens when neither attractant nor repellent exists in the environment.
Explanation / Answer
Phosphorylation occurs at ser, thr and trp amino acids or protein mainly. Sometimes his, arg, lys, asp and glu also.phosphorylated.
In gene regulation methyl group is positively charged and binds with negativity charged DNA hence increase the folding of DNA and decrease gene expression.
Flagela shows flagelary movement controlled by the use of ATP. Basala body plays important role.in that movement.
Chemoattractants attracts the cells.
Cells moves towards the high concentration of chemoattractants.
so all answer regarding this shold be given by this concept.
